For the enthusiast who wants the most from their vehicle. Engineered and dyno-tested to give you improved acceleration, maximum hill climbing, towing and passing power. Our best performing exhaust system produces maximum torque and horsepower gains at low-end (1800 to 3000 RPMS ) with a deep aggressive tone. Exits behind the rear tire near stock location. Quieter in the cab than any other performance exhaust. Fuel economy may improve as your engine becomes more fuel-efficient. Ideal system for towing. Heavy duty enough for off-road use. Typical horsepower gains average 15-20 increases.

Comments: Product is similar to Gibson 17700, posted in the reviews section.

This is a really nice cat back setup. It isn't cheap, but you get EVERYTHING you need. No need to buy clamps, etc., separately. All parts are of the highest quality. The included clamps are stainless.

My biggest beef with this is that on the Gibson web site says it WILL NOT FIT ON LIFTED VEHICLES. I called their tech support to find out why, and they couldn't really tell me. It fits fine on my lifted Jeep, although it comes close to hitting my rear lift shackle (but so did the factory exhaust). I haven't put on the included polished exhaust tip because I don't want it to get scratched up by the shackle bolt.

The pipes are a wider diameter than stock, which causes an interference problem with some shackles.

I'm not crazy about the sound, it sounds "ok." It is louder than I would prefer, but it doesn't sound overly ricer.
